The molecular geometry of silicon tetraiodide was determined by gas-phase electron diffraction at 378 K. The molecule has a regular tetrahedral shape with an Si - I bond length (rg) of 2.432(5) Å and an I⋯I nonbonded distance (rg) of 3.971(8) Å. There is an apparent anharmonicity in both the stretching and the bending vibrations, with the latter especially pronounced.
